Abstract
The invention discloses a composite phosphatizing agent with degreasing rust-removing phosphatization functions. The composite phosphatizing agent is characterized in comprising following raw materials, by mass, 10 to 20% of phosphoric acid, 10 to 20% of zinc oxide, 20 to 30% of zinc nitrate, 10 to 20% of nitric acid, 0.1 to 1% of tartaric acid, 0.1 to 1% of ammonium molybdate, 0.1 to 1% of phytic acid, 0.1 to 1% of a comprehensive phosphatization processing auxiliary agent, 0.1 to 1% of a soak degreasing special-purpose surfactant, and the balance water. A production method comprises following steps: one third of water, and phosphoric acid are delivered into the reaction vessel successively; a stirrer is turned on, and rotating speed is controlled to be 120r/min; zinc oxide is delivered into the reaction vessel slowly with stirring until complete reaction dissolving of zinc oxide is realized and a transparent solution is obtained; zinc nitrate, nitric acid, tartaric acid, ammonium molybdate, phytic acid, the comprehensive phosphatization processing auxiliary agent, the soak degreasing special-purpose surfactant, and the left water are delivered into the reaction vessel; and stirring is carried out until a transparent mixed solution is obtained.
Description
Technical field
The present invention relates to special phosphorization agent and production method before a kind of metal spraying application, especially a kind of simple to operate, film forming speed is fast, can generate on the metal surface with metallic matrix mortise and the combination phosphorization agent with degreasing derusting phosphating function of crystallization even thickness and production method.
Background technology
Metal all must carry out conversion processing to its surface before spray-coating, makes it generate conversion film.Conversion film has porousness, uniform and delicate, and coating penetrates into the sticking power that effectively can increase spray-on coating in hole, thus improves the solidity to corrosion of metal.Conversion film comprises phosphatize phosphate coat, passive film, organic membrane, rare-earth conversion coatings and colloidal sol silane film etc., wherein phosphatize phosphate coat is that it is in the salts solution of main body that metallic element is immersed in containing the specific acid phosphate such as Zn, Ni, Mn, Fe, add various composite additive simultaneously, through chemical treatment, at the Surface Creation of metallic element, there is the phosphate conversion film that certain thickness is insoluble in water.Existing Phosphating Solution, its workpiece after bonderizing, conforming product rate lower (only below 80%).The low major cause of conforming product rate is formed phosphorization membrane quality dissatisfaction (1 ~ 3g/m
2), the lubricating oil of q.s can not be adsorbed; Rete crystallization thickness is uneven simultaneously, and the lubricating oil skewness absorbed, does not have the functions such as degreasing rust cleaning, can not meet the requirement of workpiece wear resistance, solidity to corrosion and oilness.
Summary of the invention
The present invention is the above-mentioned technical problem in order to solve existing for prior art, there is provided a kind of simple to operate, film forming speed fast, can generate on the metal surface with metallic matrix mortise and the combination phosphorization agent with degreasing derusting phosphating function of crystallization even thickness and production method.
Technical solution of the present invention is: a kind of combination phosphorization agent with degreasing derusting phosphating function, it is characterized in that raw materials used and mass percent is as follows: phosphatase 11 0 ~ 20%, zinc oxide 10 ~ 20%, zinc nitrate 20 ~ 30%, nitric acid 10 ~ 20%, tartrate 0.1 ~ 1%, ammonium molybdate 0.1 ~ 1%, phytic acid 0.1 ~ 1%, comprehensive bonderizing auxiliary agent 0.1 ~ 1% soak degreasing special surfactant 0.1 ~ 1% and water surplus.
A kind of above-mentioned production method with the combination phosphorization agent of degreasing derusting phosphating function, it is characterized in that carrying out as follows: will the water of 1/3 amount that takes be calculated, phosphoric acid joins in reactor successively, start agitator and control rotating speed 120 turns/min, slowly join calculating the zinc oxide thread weighed in reactor again, stir while adding until zinc oxide total overall reaction is dissolved make the transparent shape of solution, and then take the zinc nitrate of calculated amount, nitric acid, tartrate, ammonium molybdate, phytic acid, comprehensive bonderizing auxiliary agent, the water of soak degreasing special surfactant and surplus, slowly join successively in reactor, stir while adding, until the transparent liquid of solution, blowing is packed.
The present invention is simple to operate, film forming speed is fast, and can generate the extremely strong phosphatize phosphate coat of fine crystallization, adsorptivity fast at surface of workpiece, phosphorization membrane quality reaches standard (1 ~ 3g/m
2) requirement, the lubricating oil of adsorbable q.s and being evenly distributed, can improve the wear resistance of workpiece, solidity to corrosion and oilness, have the functions such as degreasing rust cleaning, conforming product rate is improved (more than 98%).
